Question

Using SDRAM and STM32

Hello,

My questions are as follows:

1. Can I use DDR-SDRAM with FMC or should i use SDRAM only?

2. Can I use two SDRAMs and control them with "Chip Select" pin?

I want to use this SDRAM. This SDRAM is similar to used on the STM32F779EVAL board, but 512Mbit instead of 256Mnit.

thanks

Doesn't support DDR

The STM32's typically have two decode "banks" providing different chip selects, this is different from the SDRAM's internal banks.
